Why Does Fluid Speed Up as it Moves Into a Narrower Pipe? | Continuity | Fluid Mechanics

[@sixfuries7420]

Absolutely Incredible! This question has been haunting me for years-- ever since I went to an engineering summer camp and the councilor couldn't explain why this happened. Now it won't be able to keep me up at night anymore!

Why doesn’t this have many likes . Amazing explanation ❤

I’m doing medicine and revising everything. Last time I did this was 5 years back when I was in 1st year and I can say that I never understood this but now I do thank you😭😭

[@INTEGRALPHYSICS]

glad to hear.

[@ehinspections]

Great video, thank you for sharing!

[@INTEGRALPHYSICS]

You bet!

The way you actually taught physics instead of math!

[@bipl8989]

I think if you mention the law of conservation of momentum, that would explain why the reduced area is accompanied by the increase in velocity. Otherwise we have to take your word for it that A1 x V1 = A2 x V2.

[@INTEGRALPHYSICS]

Linear momentum is not conserved in the pipe taper. Volume in must equal volume out, thats what drives Qin = Qout

[@bipl8989]

@@INTEGRALPHYSICSThanks. How would you solve this if it was for a steady state mass flow of a compressible fluid?

[@bkraj26]

Wonderful explanation bro!!!

So... how does a butterfly valve slow the flow rate? When you slowly close a butterfly valve in the volume/sec rate of flow on the downstream side of the valve is slower than on the upside stream. Even the flow from a sink faucet does this... as you slowly turn off the faucet, the volume flow from the faucet slows down. That seems to be in defiance of the continuity equation. What am I misunderstanding?

[@INTEGRALPHYSICS]

The volumetric flow rate (Q) MUST be the same on both sides of a valve, unless the valve has some sort of leak. Imagine 1L/s flowed into a valve, but only 0.5L/s flowed out... The valve would burst. Along that line, Bernoulli's Eqn can not be applied across a valve because the valve introduces LOTS of friciton, thus negating Bernoulli's eqn (which relies on frictionless flow).

Which tool you use to draw? How can I have one similar

[@INTEGRALPHYSICS]

I used an ellipse stencil for the circles.

[@selimseddiki430]

little erratum at 6:44 : instead of "volume" be conserved, [more generally the mass has to be conserved, which for an incompressible fluid is equivalent]. Otherwise excellent course many thanks.

[@INTEGRALPHYSICS]

Thank you. You are absolutely correct.

ok
